Posts: 901                I really like the look of an app with Multi Segment 
Displays.
I found a really good 7 segment display here on the board.
but has anyone found a multi segment display like this for RB?
Or at least the bit map images?

How would I make my 7 segment display look like it had a piece of glass over 
the top?

Location: England                Not sure this needs bitmap images, although I 
can see that would work.
You'ld need one picture per character, held in an array, and accessed by the 
ASCII value of the letter you needed.

A less bitmappy solution would be to define each letter in binary, and 
literally draw the letters as required.

Each letter space in the display has a matrix, formed of a solid background 
color, an 'unset' color used for all the unlit dots, and a 'set' color used for 
all the lit dots.
By setting the 3 colors at runtime, you could simulate all the versions of the 
display seen there.

The letter definitions themselves appear to be defined as a 7 x 9 matrix, which 
corresponds nicely to the definitions used in old 9 pin dot matrix printers.

Here is a number 3
1111110
0000001
0000001
1111110
0000001
0000001
1111110

Location: San Diego, CA                intriguing idea...... I just might have 
to make a LED class for the fun of it....

entire ASCII character set could be stored in just over 1k of space...

Posts: 901                S-Copinger  gave me a copy of his SevenSegment canvas 
object...
Its pretty much what I need for number... but 7 segments isn't good enough for 
text..
so I've seen some nice dot matrix images in that link I posted...
